I bought this unit when it was a new product way back when. I just recently got it out of storage where it had been for lack of space (this rig is big and heavy by today's standards for a digital piano). The onboard acoustic "piano" sounds are lame but the E pianos are good, as are the harpsi and vibraphone (if you really need those things). Where this board shines though is its action. It's heavy and slow - much more like a true grand piano than anything I've tried at the stores lately. Hook it up to a good keyboard module, shut your eyes and play - chances are you'll believe you're sitting in front of the real thing. I should be ashamed of myself for keeping it out of my rig for so long.
